• Nearly $1,000,000 was donated over the last two years to local, national, and international charities, many of which serve communities where ATSG employees live, work, and volunteer.
• The company partnered with the State to open a mass COVID-19 vaccination site at the Wilmington Air Park in Wilmington, Ohio.
